JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M68 x 4 FHH and careful tooling requirements reducesThe JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify the maximum outside diameter of metric threads on components. Specifically tuned for M68 x 4, 6g right hand threads, it delivers quick, unambiguous pass fail results to support accurate quality control. Use it in incoming inspection, in process checks, or final QC to ensure parts meet the required specification. Built from hardened steel for long life, the gauge resists
